The evaluation of cerebral blood flow in premature newborns offers interesting information about cerebral circulation and, physiological flow variations. Using a high resolution probe as the Access 10 of the ATL ultramark 4 duplex scanner it was possible to define flow in the anterior cerebral artery and in the middle cerebral artery in newborns without significant pathology. This study was performed in premature babies both to evaluate the best technical solution to study these small arteries and to define a standard of flow to be used in future evaluations. By the 10 MHz focus (on the variable focus probe 5-7.5 and 10 MHz) it was observed that a smaller variation of flow determinations is obtained by the 10 MHz focus (both for the middle and anterior cerebral arteries). In conclusion duplex scanning offers probably the best solution to evaluate cerebral blood flow in premature newborns both in qualitative and quantitative way.
对早产儿脑血流的评估为脑循环及生理血流变化提供了有趣的信息。使用高分辨率探头（如ATL超马克4型双功扫描仪的Access 10），能够在无明显病变的新生儿中确定大脑前动脉和大脑中动脉的血流。本研究在早产儿中进行，旨在评估研究这些小动脉的最佳技术方案，并确定未来评估中使用的血流标准。通过10兆赫聚焦（在5 - 7.5和10兆赫的可变聚焦探头上）观察到，10兆赫聚焦时血流测定的变化较小（大脑中动脉和大脑前动脉均如此）。总之，双功扫描可能为定性和定量评估早产儿脑血流提供了最佳解决方案。
